Flex Hose

PROTAPE® PUR 330 AS is a lightweight, microbe-resistant, flame-retardant flex hose built for conveying gases along with abrasive dust, powders, and fibers. Constructed from ester-polyurethane reinforced with a spring steel wire helix, it's highly flexible and compressible at a 3:1 ratio, making it easy to route around equipment and through tight runs. Its permanently antistatic wall (in accordance with ISO 8031) makes it a dependable choice for explosion-hazard areas and static-sensitive operations.

This versatile hose suits extraction systems, dust collection and filtration equipment, oil mist extraction, and extraction arms. It's commonly used on printed circuit board drilling machines, vapor return lines, paint and spray mist extraction, textile fiber extraction, and ventilation systems for barns, clean rooms, and semiconductor production. It also performs well in surface-prep operations such as shot blasting, shipyard work, stripping, floor preparation, and grinding, and can serve as an exterior protective hose in heating applications.
